NAT Settings

If the devices are kept within a private network behind a Firewall, we recommend using STUN Server. The following settings
are useful in the STUN Server scenario:
STUN Server
Under Settings��General Settings, enter a STUN Server IP (or FQDN) that you may have, or look up a free public STUN
Server on the internet and enter it on this field. If using Public IP, keep this field blank.
Use Random Ports
It is under Settings��General Settings. This setting depends on your network settings. When set to "Yes", it will force random
generation of both the local SIP and RTP ports. This is usually necessary when multiple GSCs are behind the same NAT. If using
a Public IP address, set this parameter to "No".
NAT Traversal
It is under Accounts X��Network Settings. Default setting is "No". Enable the device to use NAT traversal when it is behind
firewall on a private network. Select Keep-Alive, Auto, STUN (with STUN server path configured too) or other option according
to the network setting.
